Our previous study showed that estrogen can induce mitochondrial adenosine triphosphate (ATP) synthesis-associated gene expressions and osteoblast maturation. Genistein, a phytoestrogenic isoflavone that is widely found in various foods and traditional herb products, is beneficial for osteogenesis by selectively triggering estrogen receptor alpha (ER[Formula: see text] expression. In this study, we further investigated the mechanisms of genistein-induced energy production and osteoblast activation. ⋯ Suppressing ER[Formula: see text] expression instantaneously lowered genistein-induced enhancements of mitochondrial energy production and osteoblast activation. Effects of genistein on ER[Formula: see text] translocation, COX I and II mRNA expressions, ATP synthesis, and osteoblast activation were further confirmed in human U-2 OS cells. This study showed that genistein can stimulate energy production and consequent osteoblast activation via inducing ER[Formula: see text]-mediated mitochondrial ATP synthesis-linked gene expressions.

This study aimed to verify the efficacy of a combined treatment of Jakyakgamcho-tang (JGT) and acupuncture (CV12, ST25, CV4) on colitis induced by dextrane sulfate sodium (DSS). Changes in immuno-mediated factors and metabolites were investigated. Colitis symptoms such as body weight loss and elevated disease activity index were alleviated by the combined treatment. ⋯ The combined treatment group induced more effective metabolite patterns than the JGT group, implying that acupuncture treatment can restore metabolic changes caused by DSS induction. These results indicate that the simultaneous treatment of JGT administration and acupuncture procedure provides better management of the immune function and inflammatory expression of colitis than a single treatment. It is assumed that intestinal microbial control can be achieved by acupuncture stimulation as well as by taking herbal medicine.

One of the most important aspects of clinical acupuncture practice, like diabetic gastroparesis, is the selection of suitable acupoints. Furthermore, it is critical to examine the therapeutic impact differences between distal and local acupoints, as well as the prescription of their combination. In this study, diabetic gastroparesis rats were treated by needling Zhongwan (CV12) and Zusanli (ST36), and then used Single Photon Emission Computed Tomography-CT (SPECT-CT) technology to assess the effects of promoting gastric motility. ⋯ Stimulating these acupoints, on the other hand, can have a different therapeutic effect. In addition, needling local and distal acupoints together can have an antagonistic or synergistic impact on specific physiological and biochemical indexes such as gastric motility, ghrelin, gastrin, and growth factor 1, among others. Our findings demonstrated the benefits of acupoints and acupuncture in the management of diabetic gastroparesis, as well as a new insight into acupuncture therapeutics.

Muscle atrophy, or loss of skeletal muscle, is caused by aging, malnutrition, immobility through injury, or diseases such as cancer. Chamomile (Matricaria chamomilla L.) contains various active components, including flavonoids, sesquiterpenes, polyacetylenes, and coumarins, and is used in various herbal medicines in the European Pharmacopoeia. In this study, we investigated the effects of ethanol extract of chamomile [Formula: see text](MC) on muscle wasting and its mechanism of action. ⋯ Of these components, the gene expression of MyoD was significantly augmented by patulitrin, herniarin, CGA, and L7G in C2C12 cells, while Myogenin-1 gene expression was increased by A7G, patulitrin, herniarin, CGA, and L7G. Moreover, TFAM gene expression and phosphorylation of AKT were increased by all six ingredients. Based on our results, we suggest MC for use as a supplement or remedy for muscle wasting, including cachexia and sarcopenia.

Linalool, a major odorous constituent in essential oils extracted from lavender, is known to have a wide range of physiological effects on humans including pain management. The substantia gelatinosa (SG) of the trigeminal subnucleus caudalis (Vc) is involved in transmission of orofacial nociceptive responses through thin myelinated A[Formula: see text] and unmyelinated C primary afferent fibers. Up to date, the orofacial antinociceptive mechanism of linalool concerning SG neurons of the Vc has not been completely clarified yet. ⋯ These responses were almost blocked in the presence of picrotoxin and strychnine. It was also found that linalool exhibited potentiation with GABA- and glycine-induced responses. Taken together, these data show that linalool has GABA- and glycine-mimetic effects, suggesting that it can be a promising target molecule for orofacial pain management by activating inhibitory neurotransmission in the SG area of the Vc.
